Description

[Detailed Description of the Invention] [Summary] Regarding a paging receiver in which selective paging is performed using a paging signal from a wireless base station, each individual's I.P.
The purpose is to easily set the D code as the calling number of the receiver, and it consists of a card league that reads data from a recording medium, an ID code holding section that holds the ID code read by the card league, and a wireless A verification section that verifies the calling number sent from the base station and the ID code held in the ID code storage section, and when the codes matched by the verification section match, it is determined that there has been a call. and a notification section that provides notification.

[Industrial Application Field] The present invention relates to a paging receiver in which selective paging is performed using a paging signal from a wireless base station.

[Conventional technology]

NTT and other companies provide a service that selectively calls the owner of a small portable receiver (paging receiver) using a wireless signal.

In these radio paging systems, a specific calling number is assigned in advance to each receiver (such as a pager), and when the calling party dials that calling number,
The receiver corresponding to the calling number can be called.

FIG. 7 is an overall configuration diagram of a conventional radio paging system. When you dial the calling number (for example, local area code + 4 digits) from the subscriber telephone 11, that number is transferred to the local exchange 12 (or PBX) and trunk circuit 1.
3, the call number is sent to the radio paging device 14 of the central base station, and the call number is stored in a register inside the IT.

The radio paging device 14 checks whether there is a subscriber corresponding to the received calling number, and if the subscriber is registered, sends the received number to the encoding device 15 and informs the caller of the current calling number. Announce that you are inside. The encoding device 15 is a circuit that converts an analog paging signal into an encoded digital selective paging signal. sent to the base station.

Each wireless base station is provided with an inter-office phase compensation device 16 for compensating for signal delay time caused by differences in transmission path length from the central base station. The phase-matched signal is sent out from the antenna 19 via the transmitter 17 as a selective calling signal.

This results in a paging of the specific paging receiver.

Next, the circuit configuration of the paging receiver will be explained with reference to the circuit block diagram of FIG. 8.

A signal received from the antenna 21 is first high-frequency amplified by a high-frequency amplifier circuit 22, and then band-limited by a band-pass filter (BPF) 23 whose passband center frequency is 250 MHz. The signal that has passed through the bandpass filter 23 is further mixed with local oscillation signals from the first local oscillation circuit 26 and the second local oscillation circuit 27 in a first mixing circuit 24 and a second mixing circuit 25, respectively.
converted into an intermediate frequency signal. This intermediate frequency signal is amplified in an intermediate frequency amplification circuit 30 and then demodulated into an original signal by a frequency discrimination circuit 31 and a low-pass filter 32. This demodulated signal is transmitted to the waveform shaping circuit 33
After being waveform-shaped by the decoder 34, it is decoded into digital data corresponding to the calling number. ROM35
The calling number assigned to each receiver is stored in the ROM 35, and the decoder 34 compares the decoded digital data with the calling number stored in the ROM 35.
When the numbers match, the sound drive section 36 is operated and the speaker 37 notifies that there is a call.

[Problem to be solved by the invention]

Incidentally, recently, various information services such as searching various databases and disclosing personal data have been provided. Generally, in these services, a personal ID number is assigned to each individual in order to identify each individual. However, the ID numbers used in each system are independent, and the current situation is that users use different ID numbers depending on the target.

Under these circumstances, since the radio calling system described above is intended for personal use, it is conceivable to use each individual's ID number as a calling number.

In that case, if the ID code used is a personal ID number that can be used commonly for the various applications mentioned above (database search, etc.), each individual can use one type of ID.
Although it is thought that convenience for the user will be improved because all that is needed is to manage the codes, such a radio paging system has not been put into practical use at present.

Furthermore, when implementing the radio paging system as described above, setting the ID number of the user who uses the receiver in each receiver is not a practical method because the number setting work is complicated.

An object of the present invention is to enable each individual's ID code to be easily set as the receiver's calling number by inserting a recording medium such as an IC card into the paging receiver.

[Means to solve the problem]

FIG. 1 is a diagram explaining the principle of the present invention.

In the figure, a card reader 1 is a unit that reads data stored in a recording medium (such as an IC card).

The ID code holding section 2 holds the ID code read by the card reader 1. In addition, the verification unit 3 uses the calling number sent from the wireless base station and the ID
This is means for checking the ID code held in the code holding unit 2.

The notification section 4 is a means for notifying the user that there has been a call based on the verification result in the verification section 3.

[For production]

In the above configuration, when an IC card or the like is inserted into the card reader 1, the personal ID code of the IC card is read and held in the ID code holding section 2. Then, in the verification unit 3, the calling number sent from the wireless base station and
A comparison is made with the ID code held in the ID code holding section 2, and if the codes match, the notification section 4 notifies that there has been a call.

Therefore, the calling number of the receiver can be easily changed by replacing the recording medium such as an IC card inserted into the receiver. At this time, if a personal ID code that is used in common with other applications is stored in the recording medium, calls can be made using the shared ID code.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is an overall configuration diagram of the radio paging system according to the present invention, and the configuration of the system is almost the same as the conventional radio paging system (FIG. 7). However, in this system, each paging receiver 19 has a structure in which an IC card can be inserted, and the personal ID code (for example, a 4-digit numeric code/or digit personal ID number, etc.) on the paging receiver 1.
9 is set as the calling number.

In addition, in response to this, on the calling side, subscriber telephone 1
By dialing the personal ID number of the called party from 1, the paging receiver 19 to which the personal ID number is set can be called.

FIG. 3 is a circuit block diagram of a paging receiver 19 according to an embodiment of the present invention into which an IC card can be inserted. In the figure, the circuits for high frequency signal amplification, intermediate frequency conversion, frequency discrimination, etc. are the same as the circuit shown in the conventional example in Figure 8, so these circuit blocks are given the same symbols as in Figure 8. Description of each circuit will be omitted. Below, circuit blocks (blocks surrounded by broken lines in FIG. 2) which are the features of this embodiment will be explained.

The IC card reader 41 is a device that reads data such as a personal ID number stored in an IC card, and notifies the control unit 44 whether the IC card is inserted or removed, and also sends the read data to the individual. (2) Output to the D holding circuit 42.

The personal ID holding circuit 42 is a circuit that holds data (personal ID number, etc.) read by the IC card reader 41 as a selective call number for the paging receiver 19. The decoder 43 is a circuit that decodes the received signal waveform-shaped by the waveform shaping circuit 33 and converts it into a calling number.

The control unit 44 reads the personal ID read by the IC card reader 41 according to the control procedure stored in the memory 45.
Writing a number into the personal ID holding circuit 42, comparing the received calling number with the ID number stored in the personal ID holding circuit 42, or when the IC card is pulled out from the IC card reader 41. This is a circuit that performs operations such as erasing retained personal ID numbers. Furthermore, the control unit 44 has a function of comparing the security code (PIN number, etc.) added to the personal ID number with the code stored in the memory 45, and only when the security codes match It can be used to make a call or to be notified with different sounds.

Next, the operation of the paging receiver 19 configured as above will be explained.

FIG. 4 is a flowchart showing the operation of the paging receiver 19 when inserting and removing an IC card.

When the IC card is not inserted, the selective call number is not set and the receiver is in a state where call acceptance is stopped (FIG. 4, 31). In the next step S2, I
Depending on the presence or absence of the detection signal from the C card reader 41, the IC
Determine whether a card has been inserted.

When the IC card is inserted, the personal ID holding circuit 4
A reception request is output to 2 to read the data of the inserted IC card (S3). Then, it is determined whether the read data is the data end or not, and all data stored in the IC card is read (S4). Once all data has been read, enter the read data as your personal ID.
It is held in the holding circuit 42 and starts to be compared with the calling number from the decoder 43 (S5).

On the other hand, if it is determined in step S2 that the IC card is removed from the card reader 41, the operation of the high frequency amplification circuit, mixing circuit, etc. is stopped, and the reception of calls is stopped (
S6). Furthermore, since the card has been removed from the IC card reader 41, the ID memory area of the personal ID holding circuit 42 is cleared, and the personal ID code stored at that time is erased (S7).

Next, the operation when an IC card is inserted into the IC card reader 41 will be explained with reference to FIG.

First, it is determined whether a radio paging signal from the base station has been received (FIG. 5, S8). When receiving a calling signal, the control unit 44 first takes in the calling number decoded by the decoder 43 (S9), and then takes in the personal ID code held in the personal ID holding circuit 42 (SIO). Then, after comparing both numbers, the received calling number is the personal ID.
It is determined whether or not it matches the D code (Sll).

At this time, if the received calling number does not match the personal ID code, the reception is terminated and the process returns to step S8 to wait for the next reception timing.

On the other hand, if the calling number matches the personal ID code,
Furthermore, the password in the received data is captured (S12),
Similarly, it is compared with the password held in the personal ID holding circuit 42 (S13). In this embodiment, a four-digit number and a four-digit password are used as the personal ID number, and a call is made when all of these numbers match.

If the PIN numbers match in the determination in step 313, this means that the received calling number matches all of the personal IDs on the IC card, so the sound drive unit 36 is operated to make the speaker 37 emit a ringing tone. (S14).

As described above, in the above embodiment, a personal ID number commonly used for various applications is stored in an IC card, and by inserting the IC card into the paging receiver 19, a calling number for each receiver can be set. I did it like that. Thereby, the calling number can be easily changed by replacing the IC card, so the receivers that can be used are not limited, and the radio calling system can be used more flexibly. For example, even when on a business trip, by inserting one's IC card into a receiver, the receiver can be used as one's own receiver.

Furthermore, the ID code stored on the IC card can be used commonly for various applications, so each individual only needs to have one type of ID code.
The LD code can be used centrally, making it more convenient. In addition, by using the above ID code as a calling number, the calling party no longer needs to remember the calling number of the receiver carried by each individual, as was the case in the past, and each individual's ID number is separate. For example, you can make a call no matter which receiver you carry.

Next, FIG. 6 is a circuit block diagram of a second embodiment of the present invention, and circuit blocks common to those in FIG. 3 are denoted by the same reference numerals.

In this embodiment, in addition to giving a sound when receiving a call, the display 47 displays the received message information (letter and numeric information). When the calling number matches the personal ID code held in the personal ID holding circuit 42, the control unit 44 first instructs the MM1 unit 46 to produce a tone, and then instructs the attached message information to be displayed. is served. The MMI section 46 is a circuit that converts the data output from the decoder 43 into data that can be displayed on the display device 47 and outputs it to the display device 47. The MMI section 46 is a circuit that converts the data output from the decoder 43 into data that can be displayed on the display device 47 and outputs it to the display device 47. Display.

In the embodiments described above, the individual is identified by the inserted IC card, but in the second embodiment, for example, a key input section is provided on the receiver side, and the user enters the password from the input section. It is also possible to display text and numerical information only when the user inputs the password and it matches the password of the IC card. Thereby, the security of information can be ensured even when various types of information are sent using the radio paging system.

〔Effect of the invention〕

According to the present invention, a personal ID code that can be used for various applications can be easily set in a paging receiver, so that the receiver that can be used is not determined, and the range of use is further expanded. Also, from the point of view of the calling side, each individual's ID
Since calls can be made by code, call management becomes easier.
